Zirkon Labs
Mobile apps, precisely cut.
We build iOS and Android apps with Flutter: one codebase, native quality.
What we build
From first prototype to published app, or from the app that stalled to the app that scales.
Flutter apps (iOS + Android)
New apps built from scratch and published to both stores from one codebase.
Consulting & app rescue
Audits, architecture, performance and migration of legacy apps.
AI-powered apps
Chat, computer vision and automation inside mobile products.
Web & backend support
Admin panels, APIs, integrations and Flutter Web.
One codebase. Two stores. Native quality.
Flutter is Google's toolkit for building iOS and Android apps from a single codebase.
- One codebase for iOS and Android. Less development time and a single team.
- Native performance. The app compiles to machine code and draws every pixel of the interface.
- Cheaper maintenance. Every fix and every new feature reaches both platforms at once.
- Ready to grow. The same code can become web and desktop when it makes sense.

Frequently asked questions
- How long does an app take?
- It depends on the scope. After discovery, you get a schedule with a firm date for each delivery.

- Do you publish the app to the stores?
- Yes. We handle publishing to the App Store and Google Play, including the review process.
- Do you offer maintenance after launch?
- Yes. We offer support plans for fixes, OS updates and new features.
